To all whom, it may concern/.j

Be it known that I, GABRIEL A. BoBRIox, a citizen of the United States,residing at Los Angeles, in the countyof Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inReceptacles for Containing Liquid Air or other Gases, of which thefollowing is a specification, reference being had to the drawingsaccompanying and forming a part of the same.

This invention is an improvement in vessels or receptacles forcontaining liquid air or other gases which cannot safely be confined inhermetically closed or sealed receivers; and the object is to provide amore effective insulation for such vessels whereby the evaporation ofthe liquid contents due to the absorption of heat from the atmospherewill be reduced to as low a point as possible.

The principle which is common to the several forms in which myimprovement is or may be carried out is that of selfinsulationthat is tosay, the cold air or gas resulting from the evaporation of a body of theliquid is caused to circulate through a connected series of concentricchambers surrounding the in the novel and effective manner hereinafterdescribed.

Heretofore it has been proposed to surround the containing vessel by twoor more concentric chambers or compartments and to'cause the expandedair or gas to pass through the said compartments in direct series; butthis plan, while effective to a certain extent, has this objection: thatthe temperature of the air or gas in eachcompartment is higher than inthat immediately adjacent to and inside of it, so that although onecompartment serves in a measure as an insulator between its adjacentouter and inner compartments there is nevertheless aninterchange of heatbetween it and the inner compartment. To avoid this, instead ofconducting the expanding air or gas directly over itself I direct itthrough every other compartmentthat is to say, I leave between twocompartments through which the current of air or gas is iiowing inseries an inert compartment filled with any suitable adiathermanousmaterial. ,To whatever extent this plan be carried out it will be foundto be attended by beneficial results, for since any given innercompartment can ab- Sorb heat only through its surrounding compartment,which latter is itself insulated by air or gas at a temperature butlittle higher than that of said inner compartment, the interchange oftemperatures between the inner and outer compartments will be very slow.

In the accompanying drawings I have illustrated the manner in which theinvention may be carried out, .the figures representing in centralyertical section three forms or modifications of the improvement.

. In each of said figures, A represents a containing vessel, whichconstitutes the inner- -most of a series of concentric receptacles,(designated by the letters B and O.) The vessel A may be designed simplyto hold a quantity of liquid air or gas temporarily to enable it to betransported from place to place or stored until used, or it may becapable of withstanding a high pressure and designed to serve as thereceiver for a refrigerating plant or the boiler for an engine. It isnot generally essential in such case that the inner compartments becapable of withstanding high pressures, as will be understood, for themain A purpose of such inner com partments is merely tocontain theliquid or to insulate the containing vessel, so as to reduce theevapora- `tion of its contents due to the absorption of heat from theatmosphere to a minimum. The inner compartment is filled through a tubec, the liquid is withd rawn or forced out through a tube D, and thepressure within it is shown by a gage E, connected with a pipe F. Thetubes or pipes c and D pass through the walls of the severalcompartments. The tube F may be connected with the inner or an outercompartment. Theconcentriccompartments are filled with a porousadiathermanous material, such as lnineral wool. From the upper portionof the inner compartment a tube G extends downward through the spacereserved for the liquid and through the walls of the said inner and itsimmediately adjacent compartment opening into the secondinsulating-compartment'O. The remaining compartments are connected inseries with this said compartment in such manner that air or gas flowingthrough the pipe G must IOO traverse each successive compartment inalternately opposite directions, escaping finally through an outlet H.There Will thus be left one compartment B adjacent to that containingthe liquid through which there is no circulation of air or gas, and anyheat which reaches the liquid must therefore traverse this compartmentafter having been taken up from the second compartment B, filled withair or gas but little higher in temperature than the liquid itself.

I have applied to the compartment B the term inert, by which I mean toimply that it is an insulator in itself or composed of in part or wholean adiathermanous substance. This principle may be carried out morefully, as shown in Fig. 2, in which every other compartment throughoutthe series is connected, so that there will be a series of inertcompartments alternating With those through which air or gas is owing.

In Fig. 3 a modied arrangement of this plan is shown, in which the topof the innermost compartment, Which aiords a channel for the expandingair or gas, is connected with the bottom ot the next but one compartmentby a pipe K, which passes through the intermediate inert compartment.

Many other modifications of the invention will readily suggestthemselves.

What I claim as my invention is- 1. A containing vessel for liquid airor other gases in combination with a series of concentric chambers orcompartments completely surrounding the same, some of which compartmentsare connected in series With the containing vessel to form a passage forthe escape of expanding air or gas, the other and intermediatecompartments being inert, as and for the purposes set forth.

2. A containing vessel for liquid air or other gases comprising incombination an inner compartment for the liquid, an inert compartmentcompletely surrounding and inclosing the same, and an outer compartmentcompletely surrounding and inclosing the inert compartment and connectedwith the inner compartment to form a passage for the circulation of theair or gas which evaporates off from the liquid in said innercompartment, as set forth.

3. A containing vessel for liquid air or other gases, comprising incombination an inner compartment and a series of concentric outercompartments each completely surrounding and inclosing the innercompartment, the alternate outer compartments being connected in serieswith the inner compartment and with the outer air respectively, to forma passage for the escape of expanding air or gas. o

4. A containing vessel for liquid air or other gases comprising incombination an inner compartment and a series ot' concentric outercompartments completely surrounding and inclosing the same, andcontaining an adiathermanous material, the alternate outer compartmentsbeing connected in series with the inner compartment and the outer airrespectively to form a passage for the expanding air or gas, as setforth.
